The roadside hawk (Rupornis magnirostris) is a free-living bird that commonly has wing injuries caused by man-made obstacles when flying. Studies that describe the topographic anatomy of the wings of this species are necessary to assist in the treatment of possible wing lesions. For this reason, the present work aimed to describe the origin and insertion of the nerves that constitute the brachial plexus in roadside hawks. Five roadside hawk carcasses donated to the Animal Anatomy Laboratory of the São Judas University Center, UNIMONTE campus, by CEPTAS (Center for Research and Screening of Wild Animals) were used for the study. The brachial plexus of the roadside hawk was formed by the union of the ventral branches of the spinal nerves located between C9-C10-T1-T2-T3. The ventral branches joined together and formed four short trunks which later united again by exchanging nerve fibers and constituting a big caliber branch. This is divided into two nerve cords (dorsal and ventral) which are destined to specific muscular groupings. The dorsal cord originates the axillary, anconeal and radial nerves, and is responsible for innervating the extensor muscles. The ventral cord originates the pectoral, bicipital, median-ulnar, median and ulnar nerves, and is responsible for innervating the flexor muscles. |
